Abstract

Flow-through raceways have velocities below that needed to remove solids from rearing areas and thus require intermittent, manual sweeping to remove the solids producing long solid residence times and exposure to mechanical breakage which results in increased phosphorous leaching and poor fish health. This SBIR proposal offers a novel moving baffle as a new technology to solve these concerns.
